SPECIFICATION forming part of Letters Patent No. 343,662, dated June 15,1886.

Applieation'filed January 19, 1886. Serial No. 189.079. (No model.

To all whom it may concern.-

Be it known that I, ALVIN O. HALL, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Copy Holders,of which the following is a specification, reference being had thereinto the accompanying drawings.

Io My invention relates to copy holders in which one of the leaves ishinged to the other and capable of being folded when out of use; and theobject of my invention is to produce an inexpensive, efficient, anddurable device to hold written or printed manuscript that is to becopied, and render said device capable of extension laterally, to evenlysupport thereon manuscript of different widths. I attain these objectsby the construction illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of the copyholder open in position foruse. Fig. 2is a longitudinal vertical section of the same. Figs. 3, 4,5, 6, and 7 represent in perspective 2 the under side of the upper boardof the copyholder, showing extensions projecting laterally therefrom.

In'the drawings, Arepresents the bottom board, and B the upper board, ofthe copy- 0 holder. These boards are hinged together at one end at a,and at about the middle of the board B and underside thereof there ishinged at b a prop, B. To receive this prop in a folded position, thetop of the board A is grooved longitudinally at A, and'to prevent thelower end of the prop from slipping while sustaining the top board, B,in any desired position notches a are made in the bottom of the groove Ato receive said lower end of the prop. To retain the manuscript upon theboard B one end of a spring-finger, B, is secured thereon at N,adjoining the upper end I of said top board, and to indicate the linethat is under copy a pointer, a, has one end made 5 to clasp and engagein grooves 11 along the left edge of the board B.

To permit this copy-holder to uniformly support wide sheets ofmanuscript, although the boards A and B are made narrow, so that it willoccupy but little space when folded, 0 additional supports are securedto and adapted to fold against one edge of the board B.

' In Fig. 1 the supports consist ofthree narrow strips, d, hinged at dto one side or edge of the board B; but the supports may also be made toslide in ways formed into said board,

as shown in Figs. 3, 4, 5, 6, and 7.

In Fig. 3 dovetailed grooves b" are made in the bottom of the board B,and flat rods d, having correspondingly beveled edges, are (0 made tofit therein. The outer ends of these rods are united by a wood slat, (1,having a vertical depth equal to the thickness of the board B, so thatwhen either extended from or closed against the side of the board itstop surface will be even with the surface of the latter. The sameconstruction is shown in Fig. 4, exceptthat the slat d is of metal, andis either soldered to the flat rods (7. or made integral therewith.

In Fig. 5 the side support is composed of a wire rod, (1 bent shape, andhas its ends inserted in deep perforations made in one edge of the boardB, and at the bends in the wire it has a slight twist upward, so thatits long straight portion (6 is on the same level with the top of theboard B. Thesame form of bent wire is used in Fig. 6; but the ends ofthe wire are retained under grooved metal caps b secured to the underside of the board B.

In Fig. 7 independent wires or pins (1 are inserted into the edge of theboard, and they are provided with broad heads (i having one point of theperiphery even with the surface of the board B, so that both edges ofthe pa per pla'ced thereon will be evenly sustained.

Having now fully described myinvention, I claim I 1. A copy-holderconsisting of a board, A, grooved longitudinally, and havingnotches onthe bottom of said groove, a board, B, hinged to the board A, a prop, B,and side supports projecting laterally from the edge of the board B, andadapted to be folded against said edge, substantially as and for thepurpose described.

2. The combination of the board B, provided with grooves I) in its topand bottom 7 surface alongside one edge thereof, the pointer 0, havingone end made to embrace the edge of the board and enter the grooves I),and the 5 spring-fi nger B with adjustable side supports projecting fromthe edge of the board B and in the same plane with its top,substantially as and for the purpose described.

In testimony whereof Iaffix my signature in presence of two witnesses.

ALVIN O. HALL.
